Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it.
In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt until well combined.
Add the cold butter pieces to the flour mixture. Using a pastry cutter or fork, cut the butter into the flour until it resembles coarse crumbs.
Stir in the dried cranberries and orange zest, ensuring they are evenly distributed throughout the dough.
In a separate bowl, whisk together the heavy cream, egg, vanilla extract, and orange juice.
Pour the wet ingredients into the dry ingredients and mix gently with a spatula until just combined. Be careful not to overmix.
Transfer the dough onto a lightly floured surface and shape it into a circle about 1-inch thick. Cut the dough into 8 equal wedges.
Place the scones onto the prepared baking sheet and brush the tops with a little extra heavy cream for a golden finish.
Bake for 18-20 minutes, or until the scones are lightly golden on top and cooked through.
Allow the scones to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
